When the Beach Boys sang "let's go surfin' now," they probably didn't have Bethany Hamilton in mind. But the six-months-pregnant surfer took that message to heart: An adorable baby bump didn't keep her off the waves!'It's been a pretty crazy last four months finding out that we're going to be parents. Life's kind of going to be changing and kind of just started to prep for bringing a new little being into the world.'She added: 'It's really exciting. I've been surfing throughout my whole pregnancy. I plan to surf as long as I can.'At 13, Bethany lost her arm, and 60 per cent of the blood in her body, surfing off the coast of Kauai when she was attacked by a shark.She did not let the incident impact her dreams of surfing, however, and she began competing professionally four years later in 2007. In 2010, she was the twentieth ranked woman among surfers.She is also a motivational speaker and tours the country telling her inspiring story.The 25-year-old was seen riding the waves off a Hawaii beach with her baby bump on show in an athletic bikini. Last month, Bethany and husband Adam Dirks revealed they were expecting their first child together. Hamilton says she plans to keep surfing for as long as possible then turn to swimming before her baby boy is born in June.

Hamilton, 25, and husband Adam Dirks, 27, made their baby announcement in February with a sweet video on Instagram and YouTube. "We have a little surprise for you ... baby on board!" Hamilton said in the video. "She's pregnant!" added Dirks.

They came in third place.She is also a motivational speaker and tours the country telling her inspiring story.Bethany cites her Christian faith as one of her biggest inspirations to pursuing her surfing career.
